Applying liquid metal to GPU!

[TheNaitsyrk]

I just applied LM on top of 10980XE and noticed 4C drop overall. Very pleased with it.

 

I want to do the same on the GPU.

 

I have Bykski 3090 FTW3 block and I'm wondering if it's all fine to use with this?

GPU temps under load without OC are 27-28C and with 500W BIOS cranked all the way up is 35C.

 

Would love to drop it a little lower. Opinions?

Some differences with gpu, like the fact that there might be more exposed traces and capacitors near the bare die, and that the heat sink might not be made for sometrhing that isn't thermal paste or pad.

I know some people who opted to use a better non-conductive thermal paste like thermal grizzly's Kryonaut. There might be better options available today or the manufacturere might use something of better quality that can only be done in manufacturing, so don't focus on a single option for what your possible solutions are.

I have Thermal Grizzly's conformal coating, and Thermal Grizzly Conductonaut. It's currently using Thermal Grizzly Kyronaut.

do you have them all in the same loop? how much fuckin radiator do you have to keep a 500W 3090 in a loop with a 10980XE under 40C

At those temps, it seems utterly pointless to introduce such a risk/point of failure.

All in the sig.

I wouldn't even bother trying to put LM on if those are the temps you get under load.

Cooling: Two Custom Loops:

1st Loop: 4x 480mm XE CoolStream radiators and 1x 240mm XE Coolstream radiator with 1x Revo D5 RGB pump and 1x Rajintek Antila D5 Evo RGB pump for CPU only cooling with 2x Koolance QDC3.

2nd Loop: 4x 480mm XE CoolStream radiators with 1x Revo D5 RGB pump and 1x Rajintek Antila D5 Evo RGB pump for GPU only cooling with 2x Koolance QDC3.

Pardon my language but holy fucking shit why do you even need liquid metal that this point, your computer might as well cool passively esp with those temps

It does actually, just not when stuff is OCed, tried running 10980XE in CB15 without fans running topped at 48C.

 

I did it because I can I guess haha

Because, reasons comes to mind.

I highly advise against doing it due to the amount of surface conductive components the gpu has. Sure the barrier will probably stop contact but it's also not flawless and not immune to time. That and the block is aluminum which liqdui metal WILL eat into and that can easily cause a leak thus killing the card and possibly other components. So basically do not do it.

Nice that's mine.

Block is copper.

It's gonna make a mess of  copper.

You'd have to clean up and re-LM every 6-9 months.

It would be a lot better with a nickel block. Skip it with copper.

It's nickel plated.

Ah, so it won't be too bad maintenance wise.

Still not a great idea. You're already running close to ambient.

To introduce LM for 1 or 2C is not a great idea.

at that point why not just hook up to a window ac unit i love that lmfao

I have that too

Oh then the info on their site is wrong it told me it was full aluminium. Copper does make a mess too. Besides you are basically as cold as it can can already. Can you measure your liquid temp in the loop? Could be that you are basically near the lowest temp the liquid can be and LM would basically not have an impact.

About 3-5c on my 3090 with 1000w bios, around 700w load in game.

Like to know what is your ambient?

What clock speeds are you seeing?

 

My ambient is 21-23C.

Ah okay, same as me but I'm on 500W BIOS.
